BLOVJ-OUT PATCH.

Application filed February 6, 1922.

T0 (aZZ 107mm. 7210.;1 concern:

' Be it known that l, RICHARD llrrnnr l'lnnnnni'. a citizen ot the Unitcr States, residing at Plainville, in the cou'snjy o1" Norfolk, gtate of Massachusetts, have invented certain new and useful improvements in Blow-Out Patches; and l do hereby declare the following tobe a full, clear, and exact description of the invention, such will enable iothers skilled in the art to which it appertains to make and use the same.

This invention relates to a. device con1- monly known as a blow-out patch for use in connection with pneumatic tires to pro tect the inner tube ot the tire against puncture through a. weak spot or blow-out hole in the outer casing or shoe, and also to prevent damage to the shoe by the bulgingor outward projection of the inner tubethrough a weakened portion of the shoe or through a. blow-out hole, causing enlargement of the latter. i

In accordance with the invention, the blow-out patch consists of a patch body of suitable material and a piece of link mesh. The patch body is preferably made of a material such as rubber or rubber fabric curved both longitudinally and transversely to conform to the shape of the tire. and split lengthwise to receive the inner tube. The link mesh covers the tread portion oi the patch and serves both to strengthen it and to position the patch in the tire. lVhen adjusted in place. the link meshlies between 35 the shoe and the patch body. and the latter then acts to protect the soft rubber oi the inner tube againstinjury which would result were the mesh in direct contact with the inner tube; and -his protection is rendered completely effective where, in the preferred form, the sub er or rubber fabric composing the patch body is iuilcanized.

The (link niesh fabric consists preferably of a. plurality of rows of lIlt-ETHLQSlllIlg links or rings, the links of adjacent rows'being tilted or slanted in opposite directions. Such a piece or mesh fabric presents surfaces on both sides of the fabric composed. of alternate ridges and depressions, which act to grip both the inner surface of "the shoe and'the outer surface of the patch body to hold the patch against creeping, and thus insure its remaining in adjusted position without the use of special anchoring means.

The piece of link mesh is preferably of a Serial No. 534,847.

since such as to extend completely around the catch, covering the whole or a part of its length, and at the edges of the mesh are means for holding it on the patch body. These means are preferably of a construe tron such as to effectively secure the respective edges of the mesh and patch body together while permitting loose fit oi the mesh on the patch bodj so that there will be no excessive strain on the piece of mesh fabric when the inner tube is inflated.

In the specific embodiment of the invention described hereinafter. the securing means for the patch body and mesh consist of a plurality ot loops attached to the edges of the patch body and arranged alternatey on opposite edges so that they can be brought together, in the closed position oi the patch, 1n registry to receive a coupling nielnber whereby the edges are held together. To these loops the mesh is secured by means of a. threading member interlocking links at or nearthe edp' ot' the loops. I i i The invention is illustrated in the accoinpanyinp; drawings, in whichl ip fl. is a. side view of portion of the outer casing or shoe of the tire and the inner tube therein, partly brokenawa'y to show the blow-out patch in position about the inner tube;

Fig. 2 is a cross sectional view of the tire shown in Fig. 1 taken through the portion of the patch which is provided with acovering of link mesh;

Fig. 3 is a view in perspective of a portion of the blow out patch and inner tube illustrating the fastening means for holding; together the edges of the patch Fig. 4 is a view in perspective of portion e patch ilhurating the inanner in link mesh is secured 'in position a side view of the section of mesh .strated in Fig. 5.

The neuinatlc tire illustrated i. the

. of tire conis the well. known for; of an outer casing or shoe 7 and an inner inflatable tub Between the shoe and inner tube is a blow-ou'tpatch 9 which consists of a patch body 10 and a strip or sleeve of link mesh fabric 11, the latter extending around the patch body and covering a portion of the length of the patch.

The piece of link mesh fabric 11 consists of a plurality of rows of intermeshing links or rings, as the links 12, 18, etc., Fig. 5, the links of adjacent rows, as those 'in the rows 12 and 13 being tilted or slanting in opposite direct-ions, as illustrated in Fig. 6, forming a plurality of alternate ridges 14C and depressions 15. Both sides of the mesh fabric therefore present surfaces consisting of a number of spaced ridges which, upon inflation of the inner tube, imbed themselves in the opposing surfaces of the shoe and patch and so act as gripping means to prevent displacement of the patch by creeping. The piece of link mesh 11 thus serves not only to position the patch in the tire but also to reinforce and strengthen the patch body. In use, the blow-out patch is adjusted in position adjacent a worn or damaged portion of the tire. Thus Where the patch is employed to protect the inner tube against puncture through a blow-out hole or weak spot in the shoe, the mesh will be positioned so as to be interposed between the damaged part of the shoe and the patch body, where it will be effective to protect the patch body against wear or injury, increasing the clurability of the patch.

The patch body 10 is split longitudinally and the edges 16 thereof are provided with fastening loops 17 which are arranged along opposite edges so that that they will, when the patch is brought to a closed position, be in registry for the reception of a coupling member 18 which is of a length snfiicient to pass through all of the fastening loops and so hold the edges 16 of the patch body together. The opening formed by the edges 16 is closed by means of a flap 19, the latter being secured along one of its edges inside the patch. Besides serving as means for securing the edges 16 of the patch, the loops 17 are employed also to secure the piece of link mesh fabric in position on the patch body. For this purpose, the edges 520- of the link mesh are secured adjacent the corresponding edges of the patch body by means of a piece of wire 21 which is threaded through rings along the edges of the mesh and through the loops 1'? as illustrated in Fig. 1.

I claim:

1. The combination with a tire having an inner tube and an outer casing or shoe, of a blow-out patch including a split patch body for adjustment in position in the tire, and a piece of link mesh fabric covering the tread portion of the patch, means disposed along the edge of said fabric to anchor it to said patch body and means disposed on the surfaces of said fabric to position said patch.

2. The combination with a tire having an inner tube and an outer casing or shoe, of a blow-out patch including a split patch body for adjustment in the tire, and a piece of link mesh fabric covering the tread portion of the patch for strengthening and positioning the latter, said link mesh consisting of a plurality of intermeshing rings adjacent rows of which are tilted or slantedin opposite directions to form a plurality of alternate ridges and depressions, and said link mesh being secured along its longitudinal edges to-said patch body. I

3. A blow-out patch comprising a split patch body, a piece of link mesh fabric extending around said patch body, and means for securing said link mesh in posit-ion on the patch body, said means being disposed along the edges of said body.

4. A blow-out patch comprising a split patch body, a sleeve of link mesh extending around said patch body, and means serving the double function of securing said link mesh to the patch body and holding together the edges of the patch.

5. A blow-out patch comprising a split patch body, a flap for closing the opening between the edges of said patch, and a piece of link mesh fabric extending around a portion of the latter, said patch body being provided with a plurality of loop members arranged alternately on opposite edges thereof, means for securing links of said mesh to the loop members, and a coupling member adapted to pass through said loop members when in registry to hold together the edges of the patch.

6. The combination with a tire having an inner tube and an outer casing or shoe, of a blow-out patch including a split patch body for adjustment in position in the tire, a strengthening fabric covering the tread portion of said patch and formed with. a surface having portions thereof adapted to enter the surface of said patch when in use, said fabric being anchored to said patch body along the split therein.

7. A blow out patch comprising a split patch body, a piece of strengthened fabric extending around a portion of said body and means mounted in said body and extending beyond the edges thereof whereby to hold said edges together, said means being further provided with portions serving to secure said fabric to said body.

In testimony whereof I aflix my signature.
